PAPER-CUP HOLDER.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application filed February 29, 1912. Serial No. 680,694.

To all whom it may concern:

Be it known that 1, DAVID F. GURTIN, a citizen of the-United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented an Improved Paper-Cup Holder, of which the following is a specification.

My invention is an improvement in sanitary paper cup holders, and has for its object, the provision of a simple inexpensive device of the character specified by means of which cups or receptacles of paper may be held during their use.

. In the drawings: Figure 1 is a perspective view ofthe improvement with the cup in place, Fig. 2 is a side view; Fig. 3 is a section on the line 3-3 of Fig. 2 looking in the direction of thearrows; Fig. 4 is a plan View of the paper sheet from which the cup is formed; and, Fig. 5 is perspective view of the formed cup, separated from the holder; and, Fig. 6 is a plan view of another form of cup sheet.

The present embodiment of the invention comprises a conical holder 1, of sheet material, a s for instance tin, or other suitable metal, the said holder being formed from a substantially semi-oircular sheet, bent into form.

The holder is split from top to bottom,

and the edges of the split are bent outwardly to form a flange 2 at each edge, the said flanges extending radially and being substantially parallel with each other. The upper edge of the holder is headed, as indi-' catedat 3. r

It will be noticed that adjacent to the holder, the flanges 2 are'close together, and diverge slightly from each other toward their free edges. A plate or strip 4 is arranged on the outer face of each flange, the plates being of somewhat greater length than the.flanges, so as to extend above the I same, as shown in Fig. 2, and each plate 1s.

provided with a longitudinal groove on its I inner face forming a longitudinal rib 5 on its outer face.

A split tube .8 is'provided for normally holding the flanges 2 clamped on the edges lid of the cup, and for holding the plates 4. in place on the flanges. over the plates, with the edges 9 of the split engaging between the ribs 5 the holder. The said tube-is resilient, and by its pressure against the plates l, clamps the flanges 2 together. A means for separat- The tube is slipped and the body of ing the flanges isprovide'd, the same comprising. lateral lever arms 6 which are preferably formed integrally withthe plates 4, as shown in Fig. 8. The tube 8 is provided withslots or openings 10' through which sa1d arms'pr0ject,.the inner edges of the slots serving as fulcra for the arms. A finger-piece in-the form ofa disk 7 is secured to the outer end/of each arm. By pressing the disks 7 toward each'other, the plates 4: will be separated or opened more or less, corresponding tothe pressure, and the Y flanges 2 of'the split tube 8 will be also sep 'arated so as to release the cup. The slots 10 in the split tube have less diameter than the disks 7, so that the tube 8 cannot be detached from the plates .4, after thedisks have been duly attached. The ribs 5. hold the tube in place, as will be readily understood. The

parts of the device are assembled as follows: The tube 8 is slipped over the ribs 5 of plates 4 and disks 7 then attached to the arms 6.

One of the lever arms 6 is offset inwardly,

as shown at 11, in Fig. 3, to limitthe movement of the arms toward each other.

1 The cupis formed from a" heet 12 of paper, cut to substantially semi-circular shape, as shown in Fig. el. The sheet is placed in l the holder 1 with the curved edge 13 substantially parallel with the beaded-edge 3 of the holder, as indicated in Figs. 1 and 2. When so placed, the edge 14 of the" sheet is doubled upon itself to form flaps 15,

'which extend between the flanges 2 of'the holder. Vhile placing the sheet, the disks 7 are pressed toward each other, to spread the tube 8, and to relax the pressure on the plates -l, which-permits the flanges 2 to separate. As soon as the sheet 12 has been so placed, the pressure on the disks 7 i'srelaxed and the tube clamps firmly on the flaps.

The sheet 12 is somewhat greater than a semicircle, the excess portion being shown below the dotted line in Fig. -.l.- The said line indicates the fold of the flaps 15. The completed cup is shown in Fig. 5, and it will henoticed that the flaps 15 are continuone at the bottom of the cup, as indicated at 1 6, and this portion 'of the sheet is pressed.

tightly together with the flaps 15, so that the cup is water tight.

' After using thecup'. the sheet may be removed, by pressing the: plates 7 together or toward each other. "Each lug (3 when the plates are pressed together, fulcrums upon that portion of the tube between the slots to mately ,one fourth cutaway,

spread the tube. After the tube is so spread,

that portion of the sheet projecting above the edge of the holder may be grasped to remove the sheet from the holder. The said portion-is designed to prevent the lips from touching the holder. r

While a sheet of the formshown in Fig. t is preferable, it is obvious that the cup 'might be formed from a simple rectangular sheet, or from any other desired shape. The rectangular form is preferable When cost is consideration, and the sheets may be supplied in the same manner as is toilet paper, that isin a roll, the individual sheets being separated by partially separating the strip of paper at spaced intervals.

It is obvious that cups of many different shapes may be formed depending upon the shape of the holder. cups may be provided With a holder shaped to suit for holding ice cream or the like.-

For making cups, theisheet is preferably of the shape shown in Fig. 6, that is approximately three fourths of a circle. The,

;end of the. said portion is cutaway or For instance, shallow notched, as at 18. A holder for making cups from the sheets shown in Fig. 6, Would be shaped like the holder shown in Fig. 2, with the exception that the cone Would be of lesser depth.

I claim: 1. In a device of the kind described, a cup holder of conical form having a longitudinal slit in its wall and the edges of said holder at said slit projecting laterally," in combination with a spring clamp arranged'to press upon said projecting edges and normally hold the edges of said slit together, and means for manually releasing the pressure of said clamp. 7

p 2. In a holder of device of the kind described, a cup conical form having a longitudinal slitv in its Wall and with the edges of said holder at saidslit projecting laterally,

in combination with a spring clamp -arranged to press upon said projecting edges ,and normally. hold the edges of said slit together and ,a pairof projecting arms upon said clamp adapted to serve as a handle for I? said holder and for manually releasing the pressure of said clamp.
